Welcome to HIWIN Ballscrews consist of a ballscrew shaft, a ballscrew nut into which the balls are integrated and the ball recir-culation system. Ballscrews are the type of threaded shaft most commonly used in industrial and precision machines. They are used to convert rotary motion into longitudinal motion and vice versa. They display great accuracy and are highly efficient. HIWIN provides a large selection of ballscrews for all your applications.

HIWIN ballscrews are distinguished by their low-friction and precise running, require little drive torque and offer good rigidity with smooth operation. HIWIN ballscrews are available in rolled, peeled and ground versions, mak-ing them the optimum product for any application. HIWIN has at its disposal state-of-the-art production facilities, highly qualified engineers and quality-assured manufac-turing and assembly and only uses high-grade materials to meet all your requirements.

This catalogue provides technical information and will help you select the right ballscrew for your application.

BallscrewsGeneral information

1. General information

1.1 Properties

There are many benefits associated with HIWIN ballscrews including high efficiency, reverse operation, freedom from axial play, high rigidity and high lead accuracy. The

1.1.1 High efficiency in both directionsThanks to the rolling contact between the shaft and nut, ballscrews can achieve an efficiency of up to 90 %. The special surface treatment used on the ball tracks in HIWIN ballscrews reduces the frictional resistance between the ball and its track.

1.1.2 Zero backlash and high rigidityThe pointed profile HIWIN uses for ballscrew shafts and nuts allows the ballscrew nuts to be assembled without any axial play. A preload is usually used to achieve the good overall rigidity and repeatability.

1.1.3 High lead accuracyFor applications requiring very high levels of accuracy, our production meets the requirements of ISO, JIS and DIN standards; but we manufacture to customer specifi-cations too.

1.1.4 Reliable service lifeWhereas the life of standard screw drives is determined by wear on the contact sur-faces, HIWIN ballscrews can be used virtually up until the end of the metalʼs fatigue life. Great care is exercised in development, choice of material, heat treatment and manufacturing, as is demonstrated by the reliability and resilience of HIWIN ballscrews over their nominal service life. With every kind of ballscrew, the service life depends

on several influencing factors including design aspects, material quality, maintenance and most importantly the dynamic load rating (C). Profile accuracy, material properties and surface hardness are the fundamental factors affecting the dynamic load rating.

characteristic properties and resultant benefits of HIWIN ballscrews are described in detail below.

The rolling motion of the balls only requires a low drive torque thanks to the high level of efficiency. Operating costs are therefore cut since less drive output is needed.

Accuracy is guaranteed by testing with our laser measurement systems and docu-mented for the customer.

Fig. 1.5 External recirculation type nut with return tubes

Fig. 1.6 Internal recirculation type nut with return caps (RSI type)

The external recirculation system comprises the ballscrew shaft, ballscrew nut, steel balls, ball recirculation system and clamping plate. The balls are placed in the ball track between the ballscrew shaft and nut. At the end of the nut, they are guided out of the ball track and back to the start via a return tube; ball circulation is therefore a closed circuit (see Fig. 1.5).

The internal recirculation system comprises the ballscrew shaft, ballscrew nut, steel balls and deflecting parts. The balls undertake just one circuit around the shaft. The circuit is closed by a deflecting part in the ballscrew nut and allows the balls to return to the start via the rear of the thread. The position of the ball deflection in the nut gives the internal recirculation system its name (see Fig. 1.6).

1.1.6 Ball recirculation systems

HIWIN ballscrews are available with three different recirculation systems.

The third type of return is the endcap recirculation system shown in Fig. 1.7. It has the same basic principle as the external return, however, the balls are returned via a channel in the ballscrew nut. The balls perform one complete cycle in the ballscrew nut. The endcap return or “internal total recirculation” provides good loading capacity with short track lengths and small nut diameters.

Fig. 1.7 Endcap recirculation type nut with recirculation system (FSC type)

1.1.5 Low starting torque with smooth operationThe rolling friction of the balls in ballscrews only requires a very low starting torque. To achieve precise ball tracks, HIWIN uses a special design (adaptation factor) and special production procedures. This guarantees that the motorʼs drive torque remains in the range required.In one particular step of manufacturing, HIWIN can check the profile of every single

ball track. A sample report of this test is shown in Fig. 1.3.Using computer-based measuring systems, the friction torque of every ballscrew is recorded and documented with great accuracy at HIWIN. Fig. 1.4 shows typical torque progress over travel.

c) In order to attain the maximum service life, a suitable oil or grease must be used. Additives containing graphite or MoS2 must not be used (see chapter 2.7).

Oil misting baths or drip oil lubrication are permitted, but direct lubrication of the ballscrew nut is recommended.

b) Select a suitable ballscrew for your application (see Table 2.3). The relevant requirements must be noted for installation. For precision-ground ballscrews with CNC machines, this means careful alignment and the corresponding type of installation; for applications requiring less precision, we recommend rolled ballscrews, which require less work when designing the type of installation and bearings.

It is particularly important that the bearing housing and ballscrew nut are as-sembled axially parallel; otherwise uneven load distribution would result (see Fig. 2.1). Radial and torque loads are also among the factors which result in uneven load distribution (see Fig. 2.1). This can cause functional limitations and shorten the service life (see Fig. 2.2).

2.1 Design and assembly information

a) Ballscrews must be carefully cleaned using benzine and oil to protect against cor-rosion. Trichloroethylene is a suitable grease removal agent for protecting the ball track from dirt and damage; paraffin is not sufficient. Damage to the ball track by pointed objects must be avoided in all circumstances. Metal particles must also not enter the ball track.

d) Select the right type of bearing for the ballscrew shaft. When used in CNC ma-chines, we recommend angular ball bearings (angle = 60°) because of their higher axial load capacity and the fact that they permit zero-backlash or pre-loaded installation. A selection of possible end machining processes and suitable floating and fixed bearings are listed in chapter 7 onwards.

e) Precautionary measures must be taken to stop the ballscrew nut once the useful path has been exceeded (see Fig. 2.3). Travel against an axial fixed stop results in damage.

Fig. 2.3 Mechanical stop which prevents the travel distance from being exceeded.

Fig. 2.4 Telescopic or bellows shaft protection

Fig. 2.5 Special requirement of bearing journal with internal recirculation system

Fig. 2.6 Area of surface hardening on a ballscrew shafth) While surface-hardening the shafts, 2 to 3 thread turns are left unhardened on the two ends adjacent to the bearings so that connection modifications are possible. These areas are marked with the symbol in HIWIN drawings (see Fig. 2.6). Please contact HIWIN if you have special requirements for these areas.

i) Excess preload results in increased friction torque which in turn causes heating and therefore a reduced service life. On the other hand, insufficient preload re-duces rigidity and increases the risk of backlash. For use in CNC machines, HIWIN recommends a maximum preload of 8 % of the dynamic load rating C.

f) In environments with high levels of dust or metal debris, ballscrews should be provided with a telescopic or bellows shaft protection (Fig. 2.4).

g) When using an internal or end cap ball recirculation system, the ball thread must be cut to the end of the shaft. The diameter of the adjacent bearing journal must be around 0.5 –1.0 mm less than the core diameter of the ball tracks (see Fig. 2.5).

Tube

Fig. 2.7 Procedure for separating ballscrew nut and shaftk) Should it be necessary for the ballscrew nut to be removed from the shaft, a tube with an outer diameter around 0.2 to 0.4 mm smaller than the core diameter of the ball tracks should be used. The nut and shaft are fitted and removed via one end of the threaded shaft (see Fig. 2.7).

2.2 Procedure for selecting a ballscrew

Table 2.1 shows the procedure for selecting a ballscrew. The usage requirements (A) can be used to determine the necessary ballscrew parameters (B). The ballscrew suited to the application can therefore be determined one step at a time following the information provided (C).

l) The support bearing needs a recess to allow for an exact fit and exact alignment (see Fig. 2.8). HIWIN recommends a recess in accordance with DIN 509 as the standard design (Fig. 2.9). The ball thread in rolled and peeled shafts emerges in the bearing installation surface. In the worst cases, the bearing installation surface becomes too small and is no longer closed in a circular fashion. The specified bearing concentricity is then no longer ensured. A smaller inner bearing diameter or an appropriately produced peeled/ground shaft without thread emer-gence will solve this problem. For secondary applications, a support ring can also be pressed on.

2.3 Accuracy of the HIWIN ballscrews

Ground ballscrews are used in situations where a high level of positioning and repeat accuracy, smooth running and a long service life are needed. Rolled ballscrews are used where the accuracy requirements are not quite as strict but the same levels of performance and service life are required. The accuracy of peeled ballscrews is between that of rolled and precision-ground ballscrews. They can take the place of certain precision-ground ballscrews of the same tolerance class in many applications.

HIWIN manufactures rolled and peeled ballscrews up to an accuracy of T5 grade (see chapters 3 and 4). Since the outer diameter of the shafts on precision-rolled balls-crews is not ground, the installation and commissioning process differs from that for ground shafts. Chapter 3 provides all the details of the properties of rolled ballscrew shafts.

2.3.1 Tolerance classThe possible applications for ballscrews range from use with very high accuracy requirements in precision measuring technology or in aircraft construction to use as a transport screw in the packaging industry. The following factors are used to determine the tolerance class: lead deviation, surface roughness, tolerances, axial play, friction torque deviations, generation of heat and noise level.HIWIN ballscrews are split into eight tolerance classes. HIWIN precision-ground ball-screws are generally defined using what is known as the “e300 value” whereas larger tolerances are permitted for rolled ballscrews being used as transport ballscrews.

Fig. 2.10 shows the measured lead trends for each level of accuracy. Fig. 2.11 shows the same details using a DIN-compliant measuring device. This diagram can be used to determine the necessary tolerance and therefore the tolerance class needed in Table 5.1. Fig. 2.12 shows the HIWIN measurement results according to DIN. Table 2.2 lists the international standards.The positioning accuracy of machine tools is determined with the ± E value using the e300 deviation. The recommended level of accuracy during use in the machine can be found in Table 2.3. The appropriate ballscrew for the application in hand can be selected using this table.

2.3.2 Axial playIf ballscrews with no axial play are needed, preload should be used and the idle torque for test purposes defined. In CNC machines, insufficient rigidity may result in backlash

2.4 HIWIN types of preload

The Gothic arch profile permits a ball contact angle of 45°. The axial force Fa, caused by outer drive forces or inner preload forces, produces two kinds of axial play. Firstly, axial play Sa, that originates from the air between the ball and ball track. Secondly, the spring compression play l, caused by the force Fn, which acts vertically on the point of contact.The axial play can be cancelled by a preload force P. This preload can be generated with a double nut, a single nut with lead offset or with preloaded single nuts by adapt-ing the ball size.

2.4.1 Preload of double nutsThe preload is generated by inserting a spacer between the nuts (Fig. 2.15). The O preload results from fitting an oversized spacer which pushes the halves of the nut apart. The X preload is generated with an undersized spacer which pulls the nuts together.If the shaft has to be stretched to increase rigidity, contact HIWIN to find out how much it needs to be stretched. (Recommended amount of stretching: 0.02 – 0.03 mm per metre of shaft length, the amount of stretching must be taken into account when defining the T value)

2.4.2 Preload of single nutsThere are two kinds of preload for the single nuts. One of these is the “preload method with oversized balls”. This involves balls which are slightly larger than the space in the ball track; the ball therefore makes contact at four points (Fig. 2.16).

The other method is known as “preload from lead offset” (see Fig. 2.17). The nut is ground such that it is offset from the central lead. This type of preload takes the place of the classic double nut preload and offers the benefit that a compact single nut with good rigidity can be used with low preload forces. This method is not, however, suited to use with high preloads and high leads. The recommend preload force is less than 5 % of the dynamic load rating (C).

2.4.3 Idle torque fluctuation(1) Measuring methodPreload produces a friction torque between nut and threaded shaft. This is measured by moving the threaded shaft at constant speed while holding the nut with a special locking device (see Fig. 2.19).

The force FPr measured by the force sensor is used to calculate the idle torque of the threaded shaft. HIWIN has developed a computer-assisted measuring device which monitors the idle torque during turning. The idle torque can therefore be set precisely to the customer specification (Fig. 1.4). The standard measuring device for recording idle torque is described in Fig. 2.18 and Table 2.11.

2.5.6 RigidityRigidity describes the flexibility of a machine element. The overall rigidity of a ball-screw is determined by the axial rigidity of the nut/shaft system, the contact rigidity of the ball track and the rigidity of the threaded shaft. The following factors should also be taken into account when fitting the ballscrew in a machine: rigidity of support bearings, assembly conditions of nuts with table etc.

The rigidity of the nut/shaft unit and the ball and ball track can be combined to pro-duce the rigidity of the nut Rn, which is listed in the dimensions tables for the different types of nuts.

2.5.8 Dynamic load rating Cdyn (theoretical)The dynamic load rating describes the load at which 90 % of all ballscrews reach a life expectancy of 1 × 106 revolutions (C). The reliability factor can be taken into account in accordance with Table 2.12. The dynamic load rating is listed in the dimensions tables for the nuts.

∆L = 11,6 × 10-6 × ∆T × ls;gesF 2.34

2.5.9 Static load rating C0The static load rating describes the load which causes permanent deformation of the ball track of more than 0.0001 of the ball diameter. In order to calculate the maximum static load rating, the static structural safety S0 of the application conditions must be taken into account.

2.5.10 Material propertiesLow noise levels are needed on high-quality machine tools even when working at high rapid motion speeds and under high load. HIWIN ballscrews achieve this thanks to high-grade recirculation systems, the special design of the ball track, well-engineered assembly procedures and careful checking of surfaces and dimensions.

2.5.11 VersionsThe maximum ballscrew length which can be manufactured depends on its diameter and accuracy. Since ballscrews with a high level of accuracy require a high degree of straightness, increasing the ratio between length and diameter not only makes manufacture increasingly complicated, the shaft rigidity is also reduced.

The dynamic and static load ratings listed in the dimensions tables are based on a surface hardness equivalent to HRC 60. For surface hardnesses of less than this, the load ratings can be determined using the following calculation.

2.6 Effects of temperature increases

An increase in temperature in ballscrew shafts during operation impacts on the accuracy of a machine’s feed system, especially if the machine has strict speed and accuracy requirements.The following factors affect the temperature increase in ballscrews:1) Preload2) Lubrication3) Stretching of the shaft

Fig. 2.24 shows the relationship between operating speed, preload and temperature increase. Fig. 2.25 shows the temperature increase in the nut depending on idle torque. According to Fig. 2.24 and Fig. 2.25, doubling the preload produces a temperature in-crease of around 5 °C, but only increases the rigidity by around 5 %, i.e. just a few µm.

30

2.6.1 Effects of preloadPreload increases the thread’s friction torque and therefore causes increases in tem-perature during operation. To ensure a long service life and low increase in tempera-ture, the maximum preload should not exceed 5 % of the dynamic load rating.Basically, ball screws should only be preloaded when it is absolutely necessary to reduce axial play.

2.6.2 Effects of thermal expansionAn increase in temperature in the ballscrew results in the threaded shaft expanding as a result of thermal loading. The shaft length may therefore vary. If you require more information about this, please contact HIWIN.

2.7 Lubrication

HIWIN ballscrews can be lubricated with grease, semi-fluid grease or oil depending on the application. They are supplied preserved as standard, but must never be taken into service without initial lubrication. For information about the initial greasing, amounts of lubricant and lubrication intervals, please consult the assembly instructions “Ballscrews”.

Table 3.2 Overview of rolled ballscrews available

3.1 Properties

One of the benefits of rolled ballscrews is that feed systems equipped with them have less friction and are quieter than standard threads.

HIWIN manufactures them using state-of-the-art rolling technologies where the processes of material selection, rolling, heat treatment, machining and assembly are very closely coordinated.

Rolled ballscrews from HIWIN can be flexibly used in virtually all areas of industry. Rolled ballscrew shafts with diameters of 8 mm to 63 mm are always kept in stock and can be supplied at short notice. They can be supplied with or without end machining. Complete bearing units combined with standardised shaft ends enable us to supply complete ballscrews.

3.2 Tolerance classes

Table 3.1 shows the tolerance classes of rolled ballscrews. The lead accuracy is defined using the deviation from nominal path over any 300 mm section of the entire length.

3.3 Nuts for rolled ballscrews

The ballscrews listed below are available ex stock in tolerance class T7 and therefore have a short delivery time. Nut types deviating from the standard for rolled ballscrews

and deviating tolerance classes can be ordered and supplied. Contact HIWIN staff for more details.

4.1 Properties

In terms of quality, peeled ballscrews from HIWIN fall between rolled and ground ball-screws and can therefore be used for numerous transport or positioning applications. On request, we are happy to produce a lead measurement report for them. A number of nut shapes are available for peeled ballscrews, as both single and double nuts.

Customised complete ballscrews can be produced with short lead times. Complete bearing units combined with standardised shaft ends minimise the amount of design work involved.

Table 4.8 Safety nut dimensions

The safety nut comprises a ball thread unit and safety unit. The safety nut basically works like a normal ballscrew nut. If the axial play is increased due to wear, ball fail-ure or ball loss, the thread of the safety unit comes into contact with the ball thread. The nut cannot therefore break out. The normal function of the unit is guaranteed up to an axial play of 0.4 mm.

Of the various production methods used for ballscrews, ground ballscrews offer the greatest accuracy. Ballscrews with a lead accuracy of up to 3.5 µm/300 mm thread length can be produced by grinding after hardening. They are used mainly in machine tools, grinding machines and measuring machines.Ground ballscrews are always customized, enabling the customer’s requirements relating to nut shape, load ratings, preload method, wiper type and end machining to be met. Contact our team for more details.

Below you will find typical standardized nut shapes, nominal diameters and leads. This is just part of our range. We can provide other nut dimensions on request.

7.1 Shaft ends and bearing configuration

To reduce the amount of design work required, we provide standardised end machining processes and bearing units. We recommend the “B”, “E” and “F” bearing series for simple applications and low axial forces. The SFA and SLA bearing units are suited to more challenging applications. The WBK series is available for heavy-duty applications. When selecting the suitable bearing type, the permissible axial force of the fixed bear-ing must also be taken into account.
